Paroxysmal atrial fibrillation is associated with poor sleep quality: Tamagawa cross-sectional study on the relationship between lifestyle and atrial fibrillation (TAMAGAWA-AF study).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Quality of life (QOL) is reduced in patients with atrial fibrillation (AF). However, data regarding the association between sleep quality, one of the major components of QOL, and AF are insufficient. This cross-sectional study aimed to elucidate whether sleep quality is reduced in patients with AF. Methods: We recruited 2054 consecutive outpatients (64 ± 10 years, 1089 men) who had regularly presented to 26 clinics affiliated with the Tamagawa Medical Association, Tokyo, Japan. The patients were divided into paroxysmal AF (PaAF), persistent or permanent AF (PeAF), and non-AF groups. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). The global PSQI score was calculated according to the answer to each question, and poor sleep quality was defined as a global PSQI score ≥6 points. Logistic regression analysis was used to obtain odds ratio for poor sleep quality in the PaAF and PeAF groups, relative to the non-AF group. Results: The PaAF group showed significantly increased odds ratio for poor sleep quality (1.49, 95% confidence interval 1.02-2.17), after adjusting for multiple potential confounders. In contrast, no significant odds ratio for poor sleep quality was observed in the PeAF group (1.09, 95% confidence interval 0.70-1.71). Among the PSQI components, poor subjective sleep quality and sleep disturbances were the main determinants of poor sleep quality in the PaAF group. Conclusion: Sleep quality was found to be reduced in patients with PaAF, and this may be attributed to poor subjective sleep quality and sleep disturbances.
